Description

PRIORITY STATEMENT

This application claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2023-0037351, filed on Mar. 22, 2023 in the Korean Intellectual Property Office KIPO, the contents of which are herein incorporated by reference in their entireties.

BACKGROUND 1. Field

Embodiments of the present inventive concept relate to a display apparatus and an electronic apparatus including the display apparatus. More particularly, embodiments of the present inventive concept relate to a display apparatus including a wire mixing structure.

2. Description of the Related Art

Generally, a display apparatus includes a display panel and a display panel driver. The display panel displays an image based on input image data. The display panel includes a plurality of gate lines, a plurality of data lines and a plurality of pixels. The display panel driver includes a gate driver, a data driver and a driving controller. The gate driver outputs gate signals to the gate lines. The data driver outputs data voltages to the data lines. The driving controller controls the gate driver and the data driver.

The display panel driver may include a demux circuit for dividing R-G-B-G data of the data driver into R-B data and G-G data. In the display apparatus including the demux circuit, a display quality may be reduced due to coupling between a data line outputting the R-B data and a data line outputting the G-G data.

In addition, the data driver may be formed in a border reduction structure in which a data voltage applied to a data line at a center of the display panel and a data voltage applied to a data line at an edge of the display panel are alternatively outputted to reduce a dead space of the display apparatus. In this border reduction structure, horizontal lines may be added to transfer data voltages to data lines at the edge, and display quality may be reduced due to coupling between the horizontal lines and the data lines.

In addition, the demux circuit may be disposed adjacent to an integrated circuit of the data driver to reduce the dead space of the display apparatus. In this case, the number of wires floating on the display panel further increases so that the display quality may further reduced due to additional coupling.

In addition, when the output of the conventional data driver is connected to the data line of the display panel as it is, a data mapping error may occur in which the R-B data are applied to G-G pixels or the G-G data are applied to R-B pixels due to the position shift of the demux circuit.

DETAILED DESCRIPTION OF THE INVENTIVE CONCEPT

Hereinafter, the present inventive concept will be explained in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram illustrating a display apparatus according to an embodiment of the present inventive concept.

Referring to FIG. 1 , the display apparatus 10 includes a display panel 100 and a display panel driver. The display panel driver includes a driving controller 200, a gate driver 300, a gamma reference voltage generator 400 and a data driver 500.

For example, the driving controller 200 and the data driver 500 may be integrally formed. For example, the driving controller 200, the gamma reference voltage generator 400 and the data driver 500 may be integrally formed. A driving module including at least the driving controller 200 and the data driver 500 which are integrally formed may be called to a timing controller embedded data driver (TED).

The display panel 100 has a display region AA on which an image is displayed and a peripheral region PA adjacent to the display region AA.

The display panel 100 includes a plurality of gate lines GL, a plurality of data lines DL and a plurality of pixels P connected to the gate lines GL and the data lines DL. The gate lines GL may extend in a first direction D1. The data lines DL may extend in the second direction D2 crossing the first direction D1.

The driving controller 200 receives input image data IMG and an input control signal CONT from an external apparatus. The input image data IMG may include red image data, green image data and blue image data. The input image data IMG may include white image data. The input image data IMG may include magenta image data, yellow image data and cyan image data. The input control signal CONT may include a master clock signal and a data enable signal. The input control signal CONT may further include a vertical synchronizing signal and a horizontal synchronizing signal.

The driving controller 200 generates a first control signal CONT1, a second control signal CONT2, a third control signal CONT3 and a data signal DATA based on the input image data IMG and the input control signal CONT.

The driving controller 200 generates the first control signal CONT1 for controlling an operation of the gate driver 300 based on the input control signal CONT, and outputs the first control signal CONT1 to the gate driver 300. The first control signal CONT1 may further include a vertical start signal and a gate clock signal.

The driving controller 200 generates the second control signal CONT2 for controlling an operation of the data driver 500 based on the input control signal CONT, and outputs the second control signal CONT2 to the data driver 500. The second control signal CONT2 may include a horizontal start signal and a load signal.

The driving controller 200 generates the data signal DATA based on the input image data IMG. The driving controller 200 outputs the data signal DATA to the data driver 500.

The driving controller 200 generates the third control signal CONT3 for controlling an operation of the gamma reference voltage generator 400 based on the input control signal CONT, and outputs the third control signal CONT3 to the gamma reference voltage generator 400.

The gate driver 300 generates gate signals driving the gate lines GL in response to the first control signal CONT1 received from the driving controller 200. The gate driver 300 outputs the gate signals to the gate lines GL. For example, the gate driver 300 may sequentially output the gate signals to the gate lines GL. For example, the gate driver 300 may be mounted on the peripheral region PA of the display panel 100. For example, the gate driver 300 may be integrated on the peripheral region PA of the display panel 100.

The gamma reference voltage generator 400 generates a gamma reference voltage VGREF in response to the third control signal CONT3 received from the driving controller 200.

The gamma reference voltage generator 400 provides the gamma reference voltage VGREF to the data driver 500. The gamma reference voltage VGREF has a value corresponding to a level of the data signal DATA.

In an embodiment, the gamma reference voltage generator 400 may be disposed in the driving controller 200, or in the data driver 500.

The data driver 500 receives the second control signal CONT2 and the data signal DATA from the driving controller 200, and receives the gamma reference voltages VGREF from the gamma reference voltage generator 400. The data driver 500 converts the data signal DATA into data voltages having an analog type using the gamma reference voltages VGREF. The data driver 500 outputs the data voltages to the data lines DL.

FIG. 2 is a conceptual diagram illustrating the display panel 100 and the data driver 500 of FIG. 1 .

Referring to FIGS. 1 and 2 , the display panel 100 may include the display region AA and the peripheral region PA. The peripheral region PA of the display panel 100 may be connected to a bending area BA. The bending area BA may include a bending line BL for folding elements toward a rear surface of the display panel 100. The bending area BA may be disposed between the display panel 100 and the data driver 500.

The data driver 500 may be formed as a type of a data driving chip DIC. The data driving chip DIC may be disposed in an integrated circuit area ICA of the data driver 500.

The display apparatus may further include a demux circuit DXA. The demux circuit DXA may be disposed between the integrated circuit area ICA and the bending area BA.

The display panel 100 is disposed on a first side of the bending line BL. The demux circuit DXA and the integrated circuit area ICA may be disposed on a second side of the bending line BL. The demux circuit DXA and the integrated circuit area ICA may be folded toward the rear surface of the display panel 100. In the present embodiment, the demux circuit DXA is folded toward the rear surface of the display panel 100 so that a dead space of the display apparatus may be reduced compared to a case where the demux circuit DXA is disposed in the peripheral area PA of the display panel 100.

The data driver 500 may have a border reduction structure in which a data voltage applied to a data line (e.g. DL3 and DL4) at a center of the display panel 100 and a data voltage applied to a data line (e.g. DL1 and DL2) at an edge of the display panel 100 are alternatively outputted. The display panel 100 may further include a horizontal line BRS1 and BRS2 to transmit the data voltage to the data line (e.g. DL1 and DL2) at the edge of the display panel 100.

FIG. 3 is a diagram illustrating an example in which coupling occurs in a demux switching structure.

Referring to FIGS. 1 to 3 , CLA in FIG. 3 indicates a switching signal of a first switch of the demux circuit DXA and CLB in FIG. 3 indicates a switching signal of a second switch of the demux circuit DXA. FIG. 3 illustrates that CLA outputs green pixel data and CLB outputs red and blue pixel data. Alternatively, CLA may output red and blue pixel data and CLB may output green pixel data.

According to an embodiment, a timing GW ON at which the gate signal is turned on may be synchronized with a timing at which CLA maintains a low level or a high level and a timing at which CLB changed from a high level to a low level or from a low level to a high level.

Accordingly, when the display panel 100 displays a zebra pattern, the luminance of the green pixel may become brighter (as indicated by a dotted line) due to coupling at the first GW ON timing so that the image may become greenish.

As such, when a data output path synchronized with CLA and a data output path synchronized with CLB are disposed adjacent to each other, a display quality of the display panel 100 may be deteriorated due to the data coupling.
